Searches for new physics at SND@LHC / Boyarsky, Alexey (Cosine, Leiden) ; Mikulenko, Oleksii (Cosine, Leiden ; Taras Shevchenko U.) ; Ovchynnikov, Maksym (Cosine, Leiden) ; Shchutska, Lesya (EPFL, Lausanne, FSL)
SND@LHC is an approved experiment equipped to detect scattering of neutrinos produced in the far-forward direction at the LHC, and aimed to measure their properties. In addition, the detector has a potential to search for new feebly interacting particles (FIPs) that may be produced in proton-proton collisions. [...]

Towards the optimal beam dump experiment to search for feebly interacting particles / Bondarenko, Kyrylo (SISSA, Trieste ; IFPU, Trieste ; INFN, Trieste) ; Boyarsky, Alexey (Leiden U.) ; Jacobsson, Richard (CERN) ; Mikulenko, Oleksii (Leiden U.) ; Ovchynnikov, Maksym (KIT, Karlsruhe, IAP ; Leiden U.)
Future searches for new physics beyond the Standard Model are without doubt in need of a diverse approach and experiments with complementary sensitivities to different types of classes of models. One of the directions that should be explored is feebly interacting particles (FIPs) with masses below the electroweak scale. [...]

Improving the potential of BDF@SPS to search for new physics with liquid argon time projection chambers / Ferrillo, Martina (Zurich U.) ; Ovchynnikov, Maksym (KIT, Karlsruhe, IAP ; Leiden U.) ; Resnati, Filippo (CERN) ; De Roeck, Albert (CERN)
Beam dump experiments proposed at the SPS are perfectly suited to explore the parameter space of models with long-lived particles, thanks to the combination of a large intensity with a high proton beam energy. In this paper, we study how the exploration power may be augmented further by installing a detector based on liquid argon time projection chamber technology. [...]

An allowed window for heavy neutral leptons below the kaon mass / Bondarenko, Kyrylo (CERN ; Ecole Polytechnique, Lausanne) ; Boyarsky, Alexey (Leiden U.) ; Klaric, Juraj (Ecole Polytechnique, Lausanne) ; Mikulenko, Oleksii (Leiden U. ; Taras Shevchenko U.) ; Ruchayskiy, Oleg (Bohr Inst.) ; Syvolap, Vsevolod (Bohr Inst.) ; Timiryasov, Inar (Ecole Polytechnique, Lausanne)
The extension of the Standard Model with two gauge-singlet Majorana fermions can simultaneously explain two beyond-the-Standard-model phenomena: neutrino masses and oscillations, as well as the origin of the matter-antimatter asymmetry in the Universe. The parameters of such a model are constrained by the neutrino oscillation data, direct accelerator searches, big bang nucleosynthesis, and requirement of successful baryogenesis. [...]

Universal approximation of continuous functions with minimal quantum circuits / Pérez-Salinas, Adrián (Leiden U.) ; Rad, Mahtab Yaghubi (Leiden U. ; U. Leiden (main)) ; Barthe, Alice (Leiden U. ; CERN) ; Dunjko, Vedran (Leiden U. ; U. Leiden (main))
The conventional paradigm of quantum computing is discrete: it utilizes discrete sets of gates to realize bitstring-to-bitstring mappings, some of them arguably intractable for classical computers. [...]

Leiden (main) ; CERN ; Leiden U.) ; Grossi, Michele (CERN) ; Vallecorsa, Sofia (CERN) ; Tura, Jordi (U. Leiden (main) ; Leiden U.) ; Dunjko, Vedran (U. Leiden (main) ; Leiden U.)
Parameterized quantum circuits have been extensively used as the basis for machine learning models in regression, classification, and generative tasks. [...]

New physics decaying into metastable particles: impact on cosmic neutrinos / Akita, Kensuke (Tokyo U.) ; Baur, Gideon (KIT, Karlsruhe, IAP ; U. Bonn, Phys. Inst., BCTP) ; Ovchynnikov, Maksym (KIT, Karlsruhe, IAP ; CERN) ; Schwetz, Thomas (KIT, Karlsruhe, IAP) ; Syvolap, Vsevolod (Leiden U.)
We investigate decays of hypothetical unstable new physics particles into metastable species such as muons, pions, or kaons in the early Universe, when temperatures are in the MeV range, and study how they affect cosmic neutrinos. [...]
